  1. Consider the flow of an incompressible fluid under steady-state in an expander:
(Fig. 14c)

Fluid-velocity is uniform at the entrance  and at the outlet . Pressures are considered also uniform at sections 1 and 2 of the nozzle. Atmospheric pressure acts uniformly on the nozzle. Calculate the pressure drop .

 

Choose CV as shown below:
